This groundbreaking research shows light can be turned into a supersolid and that it can flow with almost zero viscosity. The findings were published in Nature.
Scientists ‘freeze’ light into a supersolid using ‘quantum theatre’

A supersolid is an exotic phase of matter in which particles are arranged in a crystalline structure but also move like a non-viscous fluid
Light always travels at 3 lakh km per second in a vacuum. It cannot be trapped and solidified because the particles of light, photons, have no rest mass and don’t interact strongly with each other.
Generally, light exists only as a particle or wave. But recently, a team of researchers from Italy’s University of Pavia and CNR Nanotec reported successfully ‘freezing’ light by manipulating photons in a meticulously arranged ultra-cold environment.
